SPRING-SEAT.

Application led March 15, 1920.

T o all 'LU/tom it may concern:

Be it known that l, LEMON M. REED, a citizen of the United States, and residing at Cleveland Heights, in the county oi Cuyahoga and State of Ohio, have invented a new and useful Spring-Seat, of which the following is a specification.

This invention relates to improvements in springseats for tractors and other 'farming machines, andpertains more especially to a seat of the character indicated which cornprises two vertically spaced and oppositely arranged substantially horizontal plates and also springs supporting the upper plate from the lower plate` and has the seat-proper mounted on the upper plate.

The primary object of this invention is to suspend the lower of said plates from a bracket of the framework of the tractor or farming machine and thereby render the seat capable of being arranged lower than it said plate were mounted directly on said bracket.

Another object is to render my improved springseat simple and durable in construction, light in weight and readily applicable to said bracket.

With these objects in view, and to attain any other object hereinafter appearing, this inventionv consists in certain features ot construction, and combinations and relative arrangements of parts, hereinafter described in this specification, pointed out in the claims, and illustrated in the accompanying drawings.

In said drawings, Figure 1 is a central vertical section ot ay spring-seat embodying my invention. Fig. 2 is a horizontal section taken along the line 2 2, Fig. 1, looking downwardly. Fig. 3 is a vertical section taken along either line 3 3, Fig. 1. Fig. e is a vertical section taken along the line i-4, Fig. 1. Fig. 5 is a vertical section taken along the line'5-5, Fig. 2, looking outwardly.

Referring to said drawings, 7` indicates the upper portion ot a bracket adapted to be carried by the framework of a tractor or other vehicle or, machine at the rear end, and said bracket has a rearwardly projecting arm 8 from which my improved seat is shown supported. Said seat comprises two vertically spaced and directly opposite and substantially horizontal oblong metal plates 9 and 10 arranged over and under respec- Specication of Letters Patent.

tively and spaced from and extending longitudinally ot the bracket-arm 8, and the lower plate 10 is shown suspended from said arm by means comprising two pairs of substantially vertical bolts 12 which have their Shanks rigidly secured to said lowerv plate as will hereinafter appear. Said pairs o't bolts are spaced longitudinally or said arm. rihe bolts ot each pair oi 'bolts 12 (see Figs. 1, 2 and 3) are arranged at opposite side edges respectively of the arm 8 andY have their Shanks extending loosely through two substantially horizontal clamping bars 18 and 1i arranged respectively over and under said arm. Said bars entend transversely of said arm and beyond the .side edges of said arm. Fach upper bar V13 lies on said arm, and each lower bar 1st is arranged next the under side ot said arm. Each bolt 1.2 has its head 15 overlapping the top side ot the bar 13 penetrated by said bolt, and a nut 16 is threaded onto the shank of said bolt at the underside ot the bar 1li penetrated by said bolt., and said bars and the arm 8 are clamped together by and between said nut and said head. Preierably each bolt ot each pair of bolts 12 has its shank extending loosely through and below the lower plate 10, and nuts 1'? and 18 arethreaded onto said shank and arranged at and tightened against the upper side and under side respectively ot said plate so as to iiX said bolt to said plate.

riChe seat illustrated comprises two laterally spaced rows ot substantially vertically arranged helical springs 20. Said springs are interposed between the plates'Q and 10. The two rows of springs 2O are shown arranged adjacent opposite longitudinal edges respectively of the bracket-arm 8, and the springs of each row or" springs are spaced longitudinally ot said arm and of course longitudinally of the plates 9 and 10. Obviously therefore the bracket-arm 8 extends between the two rows of springs. Preferably each spring of each row of springs is arranged in line laterally with a spring of the other row ot springs.

By the construction rhereinbefore described it will be observed that the upper plate 9 is supported from the lower plate 10 through the medium oi two laterally spaced rows of springs, that said lower plateis suspended from the bracket-arm 8 at two points spaced longitudinally of saidrarm, and that my improved seat is arranged lower in rela'- tion to said arm than it would be if its lower plate 10 were mounted directly upon said arm. Y

To reduce the weight of the plates 9 and 10 (see Figs. 1, 2 and 5) each plate is provided at the adjacent end ot each spring "20 weight ofthe plate, and' for the same reason each plate (see Figs. l, 2 and d) is provided centrally with an opening 2a extending vertically through and longitudinally of the plate.

` Mounted on .the upper plate 9 is the seatproper 25 of my improved seat, and said seat-proper covers-the central opening 24e in. said plate-and (see Figs. l and Ll)` is secured to said plate through the medium cfa bolt 26, a nut21 and a clamping bar 28. The bar 28 overlaps the under side of the upper plate 9 at opposite sides of the opening 251; in said plate. The bolt v26 has its head countersunk in the seat-proper 25, and the: shank of saidA bolt entends loosely through Vand below the bar 28, and the nut 27 i is threaded onto said shank at the under side of said bar.

What I claim is- Y Y l. In a springfseat, two vertically spaced and .oppositely arranged substantially .herrV zontal oblongplates the upper of which is adapted tocarrythe seat-proper, two laterally spaced rows of substantially vertically arranged helical springs, the springs of each row oi? springs being spaced longitudinally of the plates and: supporting the upper plate.Y from the lower. plate, the rows of springs being tar enough apartV to permit the extension. of a bracketearm between said rows, and means for suspending the lower plate from said arm. A V

2.` In a spring-seat, `two vertically spaced and oppositely arranged substantially horizontaloblong plates the upper of which is adapted to vcarry the seat-proper, two rows of substantially vertically arranged helical springs supportingthe upper plate from the lower plate, said rows of springs being spaced laterally to permit the extension of a supporting bracket-arm between said rows, and meansfor suspendingthe lower plate from said arm at points spaced longitudinally of the plate.

3. Ina sprinCf-seat, the combination, with two vertically spaced and oppositely arranged substantially horizontal plates, and

springs supporting the upper plate from the lower plate, the upper plate having a central opening, and the seatproper ymounted on the upper plate and covering said opening, or a clamping bar extending across said opening and overlapping theunder side of the upper plate at opposite sides ot said opening, asubstantially vertical bolt having its shank extending loosely through and below said bar and having a head countersunk in the seat-proper, and a nut threaded onto said shank at the underside of said bar.

4. In a spring-seat, the combination, with a supporting bracket having a: projecting arm, of two vertically spaced substantially horizontal plates the upper of which is adapted to carry the seat-proper, said plates being arranged over and under respectively and spaced from and .extendingv` longitudinally of the aforesaid arm and'also extending laterally beyond the sideedges ofsaid arm, and springs interposed at the sides of said arm between the plates and supporting V the upper plate from the lower plate, the lower plate being suspended from said arm.

5. In a spring-seat, the combination, with a supporting bracket having a projecting arm, of two vertically spaced and substantially horizontal plates arrangedover and under respectively and spaced from and extending longitudinally of said arm and also extending laterally beyond the side edges of said arm, and springs supporting the upper plate ,from the lower plate, the lowerplate being suspended `trom said arm at points spaced longitudinally of the arm. i

6. In a spring-seat, the combination, with a supporting bracket having a projecting arm, two vertically spaced and substantially horizontal, plates arrangedy over and under respectively-and spaced troniand extending `longitudinally of said arm and also extending laterally beyond the side edges otsaid arm, and springs supporting the upper plate from the lower plate, of means ata plurality of points spaced longitudinallyof said arm for suspending the lower plate from said f arm, the plate-suspending means at each of said points comprising the following :--a pair of clamping bars which are arranged at the top and bottom respectively of said arm, two substantially vertical bolts arranged at opposite side edges respectively of said arm and having their headsy resting on the upper bar and having their shanks extending loosely through the bars and fixed to the lower plate, and nuts threaded onto Vsaid Shanks at theunder side` of the lower bar. i Y

7, In a spring-seat, two vertically spaced and oppositely arranged substantially horizontal plates lthe upperoflwhich is adapted to carry the seat-proper, substantially vertically arranged helical spacedsprings interposed between the plates and supporting the upper plate from the lower plate, the lower plate being adapted to be supported from a supporting member, each plate being provided at the adjacent end of each spring with a hole which extends vertically through the plate and is arranged in line endWise with said spring, and the plates being each provided adjacent each spring with an in Wvardly projecting annular flange which is concentric in relation to and embraced by 10 said spring.

In testimony whereof, I sign the foregoing specification, in the presence of two Witnesses.
